HUMIDIFIER AND DUST COLLECTOR FOR HEATING SYSTEMS.

Application filed April 2, 1926. Serial No. 99,317.

This invention relates to new and useful improvements in humidifiers anddust col lectors for heating systei'ns, and is an improvement upon thedevice disclosed in my copending application filed December 9,

1925, Serial No. 74,425. a y

The objectsof my present invention are to generally improve upon and mmlify the construction of humidifiers and ust collectors of the classdescribed, and to provide a device which can be readily attached inposition, presents a neat appearance, and so constructed that the dustreceivers can be readily detached for cleaning purposes. 1

Further objects of the invention are to provide a humidifier and dustcollector Which when placed in position does not obstruct the dischargeopening of the hot air register and which is provided with a sup-''porting plate adapted to be permanentl secured in position behind theframe 9 the register and can be concealed from View so that when thehumidifier is detached therefrom said plate is covered, there being onlytwo small cuts formed in the wallpaper for permitting the ends of thesupports to be inserted in the sockets in said plate.

With these and other objectsin view, my invention consists in certainnovel features of construction and arrangement of parts, hereinaftermore fully described and claimed, and illustrated in the accompanyingdrawings, in whieh- Figure l is a perspective view of my im- 85 provedhumidifier and dust collector.

the lower'portion of the humidifier and dust I collector and showingmodified means for supporting the same. y

Referringby numerals to the accompanying drawings, 10 indicates a wallregister of the hot air heating system, and interposed between the upperend thereof and wall 11 is the lowerend of a plate 12 which extendsupwardly a suitabledistance above said register. This plate is providedwith a pair of a vertically disposed sockets or seats 13 which areformed by pressing out a portion of said plate and are adapted toreceive the vertically disposed downwardly presented ends 1 1 ofsupports 15. These supports, which are preferably rectangular in crosssection, are rebent downwardly and terminate in up Wardlg presented hookportions lfiwhich are a apted to receive the lower end of a casing. 17.The front wall 17 of said casing inclines upwardly and forwardl :and isprovided with openings 18 whic are formed by striking outwardly plates19 which serve to deflectthe air through said openings 18 into thechamber 20 formed by casing 17. The bottom wall 17 of casing 17 isprovided with a, series of transverse openings 21 which also serve toadmit air into said casing. These openings are preferably formed bystriking upwardly portions of the bottom wall 17 as indicated at 22whereby said portions act as spacers and space the bottom wall of awater container 23 from the bottom wall 17 so that air can circulatearound said container. The container 23 is of smaller dimensions thanthe casing 17 so that the side walls of the former are spaced suitabledistance from the side walls of said casing and provides sufiicientclearance for the air to pass u wardly therebetween. If desired, the sie walls of the container may be inclined inwardly from the walls of saidcasing so that the air spaces between said walls increase toward the topto allow for the expansion of air and at the same time produce propercirculation thereof through the device.

The top of the casing is closed by a cover 24 the marginal edges ofwhich are rebent upwardly to reinforce said edges and are thenbentinwardly and laterally as indicated at 29 to provide horizontallydisposed flanges which when the cover is in position rest on themarginal edge of easing 17 and support said cover therein. The top andfront walls of cover 24 are provided with a series of suitable openings25 through which the air is discharged from the casing into the room.The end walls of cover 24 are provided with inwardly projectinghorizontally disposed lugs or ledges 26 which are adapted to receive theends of a removable screen member or dust collector 27. The width ofthis screen is less than the width of the cover and said screen isprefer ably positioned forwardly adjacent to the front wall of the coveras shown in Figure 5. V

Extending forwardly from the lower portion of casing 17 is an apron 28which provided with side extensions 29 which .extend adjacent to eachend wall of casing 17 and rests on horizontally disposed portions 30 ofbars 31 which latter are secured to the end wallsof casing 17. Eachextension 29 has fixed to its underside a forwardly projecting clip 32which when apron 28 occupies proper position bears against the lowerface of portions 30, thereby retaining apron 28 in roper position.

0 remove the apron from the casingit is necessary to bring said apronagainst casing 17 until clips 32 are free of portions 3O. whereupon saidapron may be lifted upwardly and then withdrawn from position.

The underside of apron 28 is provided with a pocket or dust receiver 33which opens toward casing 17 and is supported at its outer end byU-shaped clips 34 which latter are fixed to said apron while the forwardor inner end of receiver 33 is held in position by a clip 35 which ispivotally secured to said apron by a rivet 36 and may be turned on saidrivet to release said receiver so that the latter can be withdrawn fromengagement with clips 34. The lower ends of bars 31 project below thelower end of casing 17 and are preferably slotted as indicated at 37.The purpose of the slotted-ends of bars '31 is to permit attachment ofthe humidifier to supporting means 38 as shown in Figure 6. These meansare adjustable and comprise member 39 which is adapted to be fixed tothe hot air register 10 and is provided in the upper end with a seat forreceiving the lower end of member-40. The upper end of member 40 isformed with a horizontally disposed portion 41 having ahorizontallydisposed slot 42. Portion 41 is adapted to cooperate with the lower endof bar 31 and be clamped thereto by suitable fastening means 43 and theslots 37 and 42 allow adjustment of the relative arts in vertical andhorizontal planes. T is particular form of support is especially adaptedfor temporarily attaching the dust collector in position while plate 12is designed to be permanently secured in position and consequently doesnot contain the adjustable features of the other form.

The weight of the dust collector and the water container arrangedtherein is received by the upper end of register 1.0 on which the lowerend of said dust collector rests and plate 12 and supports 15 merelyhold the dust collector against displacement.

In the operation of my device, the air upon being discharged from thehot air register 10 rises upwardly and a portion thereects over the hotair register 10 and is pro-v of enters casing 17 through opening 17"while some of the air enters the casing through openings 18. The hot aircirculating through casing 17 heats the water contained in the container23. Thevapor given off by thewater mixes with the air in the chamberformed in cover 24. The dust particles laden with moisture are depositedon the screen 27 so that only pure air will be discharged through theopenings 25. Some of the air will be deflected by apron 28 into thereceiver 33 causing the dust particles to settle therein while the airwill be discharged through openings 33.
